Email alias vs multiple accounts
Three common patterns for "don't give them my real email": a stable of Gmail accounts, Gmail's "+tag" trick, or real aliases. Each solves a different shape of the problem. Here's the honest comparison.
Side-by-side comparison
Honest take on each approach
Each has a legitimate use case. None is universally right.
Multiple Gmail accounts
Pros
- +Genuinely separate identities
- +No third-party service in the loop
- +Send-and-reply works from each
Cons
- −10+ minutes to create each one
- −Phone-verification gates eventually
- −Switching is annoying
- −Gmail sometimes flags many-accounts-one-device as abuse
- −Doesn't actually hide your address — it just creates more real addresses
Verdict
Right if you want truly separate identities (work vs personal, second-life persona, etc.). Wrong if you want "hide my address from 50 retailers" — too much overhead.
Gmail "+tag" addresses
Pros
- +Free and instant
- +No third-party tool needed
- +Attribution works (you know which service leaked)
Cons
- −Doesn't hide your real address — anyone stripping +tag gets your real inbox
- −Rejected by some signup forms
- −No kill switch — every +tag goes to the same inbox
- −Filter rules pile up
- −Spammers automate +tag stripping
Verdict
Useful for attribution-only — e.g. tagging mailing lists for filter rules. Not useful as a privacy mechanism.
Real email aliases
Pros
- +Genuinely hides your real address
- +One-click create, one-click disable
- +Attribution and kill switch in one tool
- +Accepted by every signup form
- +One central dashboard
Cons
- −Requires a third-party service (us, or a competitor)
- −Free tier is finite (10 aliases vs unlimited +tags)
- −Reply-from-alias is Premium-only
Verdict
Right for almost every "I want my real address hidden from this service" use case. Wrong if you specifically need to be anonymous to the alias provider too — in which case temp-mail is your move.
Why "+tag" fails as a privacy mechanism
Gmail's "you+anything@gmail.com" trick is genuinely useful — for filtering, for attribution, for casual tracking of which service uses which list. But it's widely misunderstood as a privacy tool, and it isn't one.
The plus tag is part of the local-part. Anyone receiving you+amazon@gmail.com sees the full address, and a one-line regex strips off everything from the + to the @. The result is your real address, ready to be sold, scraped, or added to a third-party list. Spammers automate this routinely.
Real aliases are different. The recipient sees x7k9m@emailalias.io — there's no tag to strip, no real address hidden inside. If a service sells the address, they sell the alias; your real inbox stays unreachable.
Frequently asked questions
What is an encrypted email alias?
An email alias is a unique forwarding address that shields your real email. When someone sends mail to your alias, it's encrypted and forwarded to your real inbox. The sender never sees your actual email address, protecting you from spam, phishing, and data breaches.
Can I move my aliases between providers?
Aliases on a shared provider domain (e.g. @emailalias.io) aren't portable — they live on our domain and stay with us. Aliases on a custom domain (yourdomain.com) are fully portable: you keep the domain, point its MX records at a new provider, re-create the same local-parts on their side, and the addresses keep working — provided the new provider supports custom local-parts (most do; some only issue random codes). Custom domains are a Premium feature on EmailAlias, but for anyone who plans to use aliases long-term, it's vendor-independence insurance worth having.
Is EmailAlias better than disposable email services?
Unlike throwaway email services, EmailAlias gives you permanent, encrypted aliases you control. You can receive mail indefinitely, reply from your alias, and disable it anytime. It's privacy without the inconvenience. Disposable emails expire and can't receive future messages — aliases are yours forever.
What if I start getting spam on an alias?
Simply disable the alias from your dashboard. This is the beauty of per-service aliases — you can cut off spam from one source without affecting any other service. You can also create a new alias for that service if needed.
